Why You Should Update Your Current Auto Repair Invoice and Estimating Process

When you think about the most exciting aspects of being in the auto repair industry, it’s unlikely that the invoice and estimating process comes to mind. Drafting up invoices and getting approval on estimates can be a tedious process when all your team wants to do is get things rolling with the repair! And if you have a small team, it might be tough to find someone who can squeeze in the time to create an estimate and invoice for every single repair.

However, the auto repair invoice and estimating process is one of the most important parts of your business. By fine-tuning it, you can keep better track of repairs and sell more work, increasing your shop’s ARO.

Here are five main reasons why you should fine-tune your shop’s auto repair invoice and estimating process.

1. Meet Any Relevant Compliance Standards

Depending on which state you’re operating your auto repair business in, you might be legally required to give customers an estimate before the technician begins working on the car and an invoice when the work is completed. Some states with a variation of this law include California, North Carolina, and Washington.

No matter which state you’re in, it’s a good idea to brush up on the latest applicable laws to make sure that your shop is in compliance. When you’re managing your team and growing your business, the last thing you want to deal with is a legal hurdle.

2. Provide Better Customer Service

Legal compliance aside, fine-tuning your auto repair invoice and estimating process helps you provide better customer service.

Think about it this way: when you go shopping, you want to see the price tag on an item before deciding to make a purchase. For your customers, getting an estimate is akin to seeing the “price tag” on an item before committing to a purchase. When customers get an estimate from you, they’ll feel more at ease and secure with getting a repair from your shop. In addition, they’ll know that you care about their experience and will be impressed by your team’s professionalism.

When a service advisor sends a customer an estimate, both parties are essentially signing off on a contract, stating that they understand the nature of the repair work to be performed and the cost. If a repair doesn’t go as planned or the cost is higher than expected, the customer will hold your shop accountable. Likewise, once the customer receives the invoice, if they walk back on a repair they signed off on or don’t pay, you can hold them accountable.

3. Minimize Chargebacks and Loss of Money

A major benefit of that increased accountability is that you’ll minimize chargebacks, and your shop will lose less money.

Imagine that you don’t have a refined repair invoice and estimate process in place. Your customer might have fuzzy expectations going into the repair. Then, once it’s time to pay, they gawk at the price—they didn’t think it would be that much. They might argue back-and-forth with the service advisor, and you might get dragged into the argument. Finally, things settle down, and the customer pays. You think everything is okay. But a few days later, you see: a chargeback!

Suddenly, you have a new headache on your hands that you need to solve to ensure that your team is compensated for their hard work and that your shop doesn’t take a financial loss.

By providing each customer with an estimate and invoice, you’re showing them exactly what to expect. They will have transparency into the repair process and aren’t surprised when it’s time to pay. As a result, you avoid wasting your valuable time and energy on chargebacks and safeguard your shop from financial loss.

4. Use Declined Jobs to Keep Better Records for Future Repairs

A fine-tuned auto repair invoice and estimating process not only safeguards your shop from chargebacks and financial loss but also helps your shop upsell work in the future. Any repairs your customers decline on an estimate can be sold back to them at a later time.

When a service advisor gives a customer an estimate, there’s a chance that they may not approve every listed job, especially the non-urgent repairs. They might decide to come back to your shop in a few months, once the repair is necessary. However, customers might forget to do so, and your team might, too. But with a structured invoice and estimate process in place, service advisors can keep track of declined jobs. From there, when the time rolls around for those turned-down repairs, the service advisor can notify the customer.

5. Increase Your Shop’s ARO

A transparent, effective auto repair estimate process starts with a digital vehicle inspection (DVI). When a service advisor sends a customer a DVI, the customer will be able to look at the attached photos and videos of their vehicle, as well as the proposed repairs and the urgency of those repairs.

Because the customer will see exactly what’s wrong with their vehicle, they’ll be more likely to sign off on all the work, rather than just what they think they need. The photos and videos paint a clearer picture of the necessity of each repair. As a result, you’ll sell more work per individual ticket, and your shop’s ARO will increase.

How to Fine-Tune Your Auto Repair Invoice and Estimating Process

While paper invoices and estimates might work in the short term, they’re not sustainable—and we’re not just talking about the environment. An ever-expanding paper trail means that service advisors will have to hunt down individual estimates in messy file folders, customers might misplace their estimates, and more.

A shop management system like Tekmetric can streamline your auto repair invoice and estimating process.

With Tekmetric, a service advisor can create a repair order and dispatch it to a technician to run an inspection. Once the technician conducts the inspection, the service advisor can send the customer a DVI, which will outline the exact repairs their vehicle will need. From there, the customer can approve or decline individual line items on the repair order, directly from their phone.

In order to prevent sticker-shock, Tekmetric separates the inspection and estimate sections. When customers open the DVI, they will first see the photos, videos, and other repair details. Once they scroll down, they’ll see the pricing.

When customers finish clicking through the estimate, designating the jobs they approve and decline, the shop has the go-ahead to start the repair. There’s a digital record of exactly what the customer approved, so when it’s time to pay, there are no surprises—and the customer drives off happy, leaves a good review, and refers your shop to their family and friends.

When you started your shop, you probably had to get the word out there. Maybe you passed out cards at your gym or got your family to tell all their friends about your new business.

Today, you likely have a loyal customer base. Your regulars drop by whenever they need repairs, and they probably also recommend your shop to their friends and family. That word-of-mouth marketing is immensely valuable. After all, new folks can’t come to your shop if they don’t know about it!

But even with loyal customers who spread the good word about your shop, you’ll eventually hit a plateau. People don’t have an endless number of friends and family in the area that they can keep referring your shop to.

You track your ARO. Maybe you watch your car count week over week. You know when a month is good and when it's below par.

But here's a question most shop owners can't answer quickly: Compared to shops like yours, are your numbers strong, average, or quietly underperforming?

There's a real difference between a number that's improving and a number that's competitive. A shop can grow ARO year over year and still be well below what high-performing shops are seeing in their market. Without an external reference point, you don't know which situation you're in.

That's the problem benchmarking solves, and it's the reason the data matters more than the direction.

Internal Tracking Tells You the Trend. Benchmarking Tells You the Truth.

Internal performance tracking is essential. If you don't know your ARO, car count, parts margin, and effective labor rate, you're managing without the most basic tools. But internal tracking has a structural limitation: it can only tell you how you're doing relative to your own history.

That's useful for spotting momentum — a rising ARO, a growing car count, tighter parts margin. What it can't tell you is whether your baseline is strong or weak relative to the market.

A shop with a $580 ARO that has grown from $520 over two years has made real progress. But if top-performing shops in their region are averaging significantly higher, that progress hasn't closed the competitive gap. It's just moved in the right direction.

The fix isn't to stop internal tracking. It's to add an external benchmark so you know what the target actually looks like.

The Problem With Benchmarking From Anecdotes

Many shop owners get their benchmarks the informal way: conversations with peers at trade shows, numbers shared in coaching groups, or revenue figures posted in forums. These have real value, but they're also limited.

Self-reported numbers skew high (people share their wins). Peer groups are small samples. Industry averages from trade associations are often lagged and lack the granularity you need to compare fairly — a six-bay shop in a suburban market shouldn't be benchmarking against national averages that include dealership-adjacent shops in metro areas.

The more useful comparison is data drawn from shops operating in similar conditions, at similar scale, tracked in a consistent and anonymized way.

What Good Benchmarking Actually Looks Like

Effective benchmarking for an auto repair shop compares you on the four metrics that most directly drive profitability:

  • ARO: Are you getting full value from each car that comes through your door?
  • Car count: Is your volume where it needs to be to support your revenue goals?
  • Parts margin: Are you protecting margin as supplier costs fluctuate?
  • Effective labor rate: Is your real revenue per labor hour aligned with your posted rate?

Each of these metrics has a different lever. If your ARO is lagging, the fix usually involves inspection completion rates or customer communication. If your car count is stagnant, the issue is typically acquisition or retention. If your parts margin is eroding, your pricing matrix needs a look. If your effective labor rate is low, it's often a discounting or packaging problem.

Benchmarking tells you which problem to solve first. That's valuable when you have limited time and you're trying to prioritize.

What to Do After You See Your Rankings

The benchmarking data is the starting point, not the finish line. Once you know which metric is your biggest gap, you can start asking the right questions:

  • If ARO is lagging: How consistently are your technicians completing and sending digital vehicle inspections (DVIs)? Are customers seeing and approving the recommended work?
  • If car count is flat: Are you actively pursuing new customers? Are return visit intervals optimized? Are declined jobs being followed up?
  • If parts margin is soft: When did you last review your parts pricing matrix? Is it adjusting for recent cost increases from your vendors?
  • If the effective labor rate is low: Are service writers building jobs accurately? Are discounts being applied consistently or inconsistently?

Each of these questions points toward a workflow, and Tekmetric's reporting is built to surface the answers at the job, technician, and service writer level. But even before you get to that step, knowing which question to ask is most of the work.

The Shops Getting This Right

High-performing shops don't treat benchmarking as a one-time exercise. They check their rankings periodically, track how their numbers shift against the industry baseline, and use the comparison to coach their teams with context.

"You're at 85% DVI completion" is a data point. "You're at 85% completion, and top shops are at 95%" is a coaching conversation with direction.

"Seeing them take the shift to Tekmetric and then grow profitability in the same four walls has been phenomenal. Some of them are just exponential."  — Matt Schwab, Clutch Automotive, Tekmetric Customer

As much we like to think we’ve always been at the top, no one is born a boss. Before you became an auto repair shop owner, you probably held other positions and had someone else bossing you around. Think back to those bosses, and how you felt about those jobs.

You may have had some bosses who you didn’t like. Their leadership style might have been too aggressive, or maybe they didn’t take the time to show you the ropes.

But hopefully, you had at least one boss who helped you get to where you are today. Typically, good bosses:

  • Strongly support your career growth by encouraging you to gain new skills
  • Understand when you have to take some time off or shift your work hours
  • Trust you to get the job done instead of micromanaging you
  • Show you they value your contributions to the team
  • Effectively communicate instructions and priorities to you

If you had a supportive boss who championed you at work, you probably went above and beyond—you knew they valued your work. Your former boss’s great leadership qualities probably set an example for you, influencing how you run your own shop today.

We’re willing to bet you’re already an excellent leader, running your own shop in a way that inspires your team, just like how your previous bosses might have inspired you. But, just like you expect your employees to grow in their roles, your employees expect you to continue growing as a leader.

By fine-tuning your leadership skills, you can bring the absolute best out of yourself and your team.
